Vertically move distance and move cut-parts for d, complete cut-parts to horizontal stripe.
The invention has the beneficial effects as follows: a kind of clothing cut-parts based on images match method to horizontal stripe, it is not necessary to hands
Work mode is to horizontal stripe, and the method uses image processing techniques to calculate the anglec of rotation and the displacement needing the cut-parts to horizontal stripe,
Thus move for mechanical hand, cut-parts offer foundation is provided.
Accompanying drawing explanation
Fig. 1 is a kind of based on images match the clothing cut-parts using the present invention flow charts to the method for horizontal stripe.
Detailed description of the invention
The present invention is described in detail with detailed description of the invention below in conjunction with the accompanying drawings.
The invention provides a kind of clothing cut-parts based on images match method to horizontal stripe.
A kind of clothing cut-parts based on images match method to horizontal stripe, as it is shown in figure 1, specifically real according to following steps
Execute:
Step 1, the cut-parts sewing up needs carry out image acquisition;
Step 1, particularly as follows: the cut-parts sewed up will be needed to be positioned on solid background plate, uses the pixel phase more than 5,000,000
Machine gathers image;
Step 2, the image collected is carried out image gray processing;Due to collected by camera to image be RGB image, directly
Process data volume is big, and cut-parts segmentation is less demanding to color, therefore coloured image is carried out gray processing process,
Step 2 carries out image gray processing according to formula (1),
Y=0.299R+0.587G+0.114B (1)
In formula (1), Y is brightness, and R, G, B are respectively the component that coloured image is red, green, blue;
Step 3, image to gray processing carry out Threshold segmentation, it is thus achieved that several cut-parts bianry images;
Image segmentation is the dividing processing by acquired original image carries out certain mode, in order to carry from its result
Get the process of some feature (such as profile, region etc.) of image, owing to the image that collects comprising the front width of cut-parts simultaneously
Back panel, therefore needs to extract front and back's width respectively, is divided into a pair cut-parts, and striped alignment between a pair cut-parts, for adopting
The image that collection arrives, uses threshold Image Segmentation method;
Step 3 uses threshold binary image method that the image of gray processing is carried out Threshold segmentation,
Threshold calculations is carried out according to formula (2),
In formula (2), Z2Representing the bianry image after threshold operation, (x, y) represents original image pixels value to f, and T represents institute
If threshold value, the span of T is 160-180;
Step 4, to needing the every pair of bianry image to horizontal stripe to use Hole filling algorithms to carry out holes filling, use morphology
Closed operation eliminates the jagged edges in cut-parts every pair bianry image;
There is hole in the bianry image being partitioned into due to reasons such as object complexity, these holes have impact on the complete of image object
Whole property, simple Morphological scale-space cannot fill up these holes completely, and Hole filling algorithms can quickly be filled up in enclosing region
Hole not of uniform size;
In step 4, closing operation of mathematical morphology is processed as expanding image, corroding, the area pixel size that burn into expands
Being about 20 × 16, burn into expansion structure element pixel size is 11 × 11;
Hole filling algorithms can effectively eliminate inner void, but yet suffers from zigzag at boundary member, and i.e. part is on limit
Half hole of edge is not padded;Expand image, corrode, i.e. closing operation of mathematical morphology processes, it is possible to fill edge disappearance
Part, eliminates jagged edges, is conducive to extracting cut-parts shape completely.Expand, corrosion can reduce from boundary direction, increase
Image size, the region that burn into expands depends on the size of structural element, the sawtooth sunk edge area size that threshold value produces,
Its pixel size is about 20 × 16, selects 11 × 11 rectangular configuration elements expansions, corrosive effect preferable;
Step 5, every pair of cut-parts bianry image are made and computing with the artwork of image acquisition in step 1, it is thus achieved that every pair is partitioned into
Cut-parts image;
Step 6, the cut-parts image being partitioned into every pair carry out cut-parts positive direction correction respectively;
The cut-parts that collection is arbitrarily put, as input picture, cause direction different, are difficult to obtain template and mate object, because of
This, need to be corrected cut-parts;
Step 6 carries out cut-parts positive direction correction and specifically implements according to following steps the cut-parts image being partitioned into;
Step 6.1, the cut-parts image Q being partitioned into is solved minimum enclosed rectangle C, obtain minimum enclosed rectangle central point
C(x, y);
Step 6.2, the minimum enclosed rectangle long side direction vector is made with horizontal line angle to beWith C(x, y)For the center of circle by cut-parts
Rotate counterclockwiseAgain to image Q1Make minimum enclosed rectangle C1, try to achieve minimum enclosed rectangle C1Rectangular centre
C(x1, y1)And rectangle length of side L1With wide L2, with A width of L is made for rectangular centre2, a length ofRectangle C2, ask
C1And C2Cut-parts size Area in two rectangles1And Area2, understand according to the observation, before and after just putting, above width, area is less than
Area under, if Area1≤Area2, then cut-parts direction is positive direction;If Area1> Area2, then with C(x1,y1)For the center of circle, will cut out
Sheet rotates 180 °, finally gives cut-parts positive direction position;
Step 7, choose every pair of region that wherein width cut-parts are waited in sewing as template;
Cut-parts texture occurs in whole cut-parts repeatedly, arbitrarily intercepts template and matched position can be caused to offset, every a pair sanction
Sheet seam area bottom curve radian is similar, can regard near symmetrical as, and this arcuate portion can be unique matching area, with
Time, the reduction of template and object search area is conducive to computer disposal speed to improve,
Step 7 chooses every pair of region that wherein width cut-parts are waited in sewing: choose every pair wherein
One width cut-parts wait that the zone level direction in sewing comprises 1 to 2 minimum cells, and vertical direction comprises 3 to 6 minimum lattice
Subelement, stencil-chosen region treats sewing part in cut-parts, and comprises part non-cut-parts region, and search graph is to be matched as choosing
/ 6th size area of cut-parts, comprise sewing texure, and error deviation is minimum;
Step 8, mate another width cut-parts region to be sewed, it is thus achieved that peak response position;
Step 8 utilizes Cross Correlation Matching algorithm based on gray scale, mates another width cut-parts region to be sewed, it is thus achieved that maximum sound
Answer position, particularly as follows:
Size M × N image f (x, y) in move the subimage w of size J × K point by point (x y), make initial point and the point of w
(x, y) overlaps, and calculates the sum of products of the image-region respective pixel covered by w in w with f, using this result of calculation as relevant
Image (x, response c y) put (and x, y), with cross find peak response determine optimal matched position, formula such as formula (3) institute
Show:
In formula (3), (x, y) is cross-correlation calculation response value to c, and its value is between 0 to 1;(x y) is matching template to w;f
(x y) is searched object;
(x, y) matrix, (x, y) in matrix, maximum is c (xMax, yMax) to c to calculate c by formula (3);
